Rob Reves-Sohn

An Associate Scientist in the WHOI Geology and Geophysics Department,
Sohn is a geophysicist and marine seismologist and will serve as the
chief scientist for the Gakkel Ridge
expedition. He earned a bachelor's degree in mechanical engineering
from Purdue University and a doctorate in oceanography from the Scripps
Institution of
Oceanography. He wrote: "The notion of using autonomous underwater
vehicles (AUVs) to get under the Arctic ice pack came to him while
playing with a Sesame Street submarine and giving his (then) newborn
(now 8-year-old) daughter a bath."

Humphris is a WHOI Senior Scientist and chair of Geology and Geophysics
Department. From 2000-2004, she served as the first director of the
WHOI Deep Ocean Exploration Institute. She is also one of the creators
of the Dive and Discover education web site, which will be following
the Gakkel expedition with daily updates. Humphris is a geochemist who
specializes in the geology and chemical composition of hydrothermal
vents, and she is a veteran of many seafloor visits in the Alvin
submersible. She earned a bachelor's degree in environmental science
from the University of Lancaster, and she earned her doctorate in
chemical oceangraphy from the MIT/WHOI Joint Program.

Hedy Edmonds is a marine geochemist at the University of Texas Marine
Science Institute and a 1997 graduate of the MIT/WHOI joint graduate
program. She will lead the water column chemistry program on the Gakkel
Ridge expedition, using conductivity-temperature-depth (CTD)
instruments to locate the hydrothermal plumes and guide AUV
deployments. Edmonds sailed on the 2001 AMORE expedition that first
found evidence of hydrothermal vents in the Arctic.

An associate scientist in the Biology Department of the Woods
Hole Oceanographic Institution, Shank is the lead biologist on the
Gakkel Ridge expedition. He specializes in the ecology and evolutionary
genetics of hydrothermal vent creatures. He earned bachelor's and
doctoral degrees at the University of North Carolina and Rutgers
University, respectively.

Hanu is an associate scientist in the WHOI Department of Applied
Ocean Physics and Engineering. He developed and led construction of the
Puma and Jaguar autonomous underwater vehicles, as well as the Camera
Sampler (Camper). He will serve as lead engineer on the Gakkel Ridge
expedition. He earned degrees in computer science and electrical
engineering from George Mason University, while completing his
doctorate in the MIT/WHOI graduate program.

Peter is an assistant scientist in the Department of Physical
Oceanography at WHOI, and a frequent visitor to the Arctic for
research, where he studies ocean circulation and its implications for
climate. Winsor earned his master's and doctoral degrees in
oceanography from Goteborg University in Sweden.

The Woods Hole Oceanographic Institution is dedicated to research and education to advance understanding of the ocean and its interaction with the Earth system, and to communicating this understanding for the benefit of society. Learn more »
